conventional VS synthetic

i heard once if you switch to synthetic its bad for the engine if you go back to conventional?

Nope. That's a bunch of hooey. The reason I am not going back to conventional oil is simply because synthetic makes it run better and shift smoother, nothing to do with going back and forth being bad for the engine.

lol alright man thanks

I'd like to know How. It's one question I always ask when someone tells me a "mechanic tip". How can it damage the motor? If they can't answer, I ignore them. The "I dont know, but I'd rather be safe than sorry" doesn't fly with me. Superstition.

dose royal purple make anything specific for bikes yet???

[QUOTE=Chango;704386]Nope. synthetic makes it run better and shift smoother,QUOTE] +1 I can vouch for this...I ran fully sythetic Motul in all my bikes and they ran and shifted much smoother and also stayed cooler in the Florida summers.

if anything using synthetic is bad for your motor...there is no petrolium in a full synth oil. and it does not stick to things like petrolium will. so over extended periods of time, there will be exposed metal surfaces that could be apt to rust, especially in the more humid climates. i swear by syntheitc blend oil, you still see the advantages of the sythetic, and it still contains good ol' petrolium oil.

This is an issue for motors that sit idle for long periods of time (weeks) but not those that are operated daily or even weekly.

What about those of us that have to let our bikes sit over winter? There are a lot of winter storage threads, but yes, if you do an oil change before winter storage, you are well advised to use standard oil so it can help protect from corrosion internally. Or use a synthetic blend if you're going to take it to the next mileage interval for change after you take it out of storage. That said, it's doubtful you would have a problem with full synthetic as long is you did a fresh change before storage and stored your bike in a dry place.

While i agree with this statement, i personally had nothing but clutch problems on my '05 750 after introducing synthetic. I believe this was intially due to the mechanic using straight synthetic instead of mixing. Clutch would slip between shifts, exceleration, down shifting etc etc...I drained it, took out the clutch pads, put in new and added a 50/50 mix, i still had issues and ultimately had to switch back to standard oil. I think my situation was created by using straight synthetic to begin with, or the clutch wasnt properly adjusted....point is i think i was partially to blame but could never quite get the problem corrected in its entirety. Anyone else have this issue? Id like to put syn in my 1000 but am afraid of the same thing happening again.

I never had that problem. I switched straight to full synthetic on my 05 600, the 06 600, and now my 08 R6S with no slipping whatsoever.

This is an issue for motors that sit idle for long periods of time (weeks) but not those that are operated daily or even weekly. i agree with you but not everyone rides their bikes everyday, or every week even, maybe once a month. there are people that dont put 1000mi a year on their bike and dont consider it being 'stored'.

i agree with you but not everyone rides their bikes everyday, or every week even, maybe once a month. there are people that dont put 1000mi a year on their bike and dont consider it being 'stored'. Well, just like in a similar thread, that's the reason why you would go with a semi-synthetic. I have run full synthetic in my 05 750 for over 60,000 miles, and never had a clutch slippage issue.

NO OIL THAT IS APPROVED FOR A WET CLUTCH NO MATTER WHAT ITS CHARACTERISTICS ARE SHOULD CAUSE ANY TYPE OF DAMAGE TO ANY PART OF A MOTOR IF IT IS BEING USED IN ACCORDANCE WITH THE OWNERS MANUAL OF THE BIKE

I knew what problem was right away as i had had no problems prior to doing this. I consulted with others, perhaps even on the site as well and had been told that using synthetics can make the clutch slip under high stress conditions. I replaced the clutch plates simply to ease my mind and methodically attempt to correct the situation. No mechanic "mixed" anything, the second go around was a blend smartguy.

either you are mentally retarded, or full of shit. read what you wrote before trying to cover your ass.

Love fest terminated.
